The effects of QMix and EndoActivator on postoperative pain in mandibular molars with nonvital pulps: a randomized clinical trial

Abstract

Aim

The purpose of this study was to compare the effects of different irrigation solutions when used EndoActivator on postoperative pain.

Methodology

A total of 104 subjects with nonvital pulps were selected and randomly assigned to four experimental groups; (G) 1 (n = 26) 2.5% NaOCl + conventional endodontic syringe, (G) 2 (n = 26) 2.5% NaOCl + EndoActivator, (G) 3 (n = 26) 2.5% NaOCl + QMix + conventional endodontic syringe, (G) 4 (n = 26) 2.5% NaOCl + QMix + EndoActivator. All the patients were prescribed ibuprofen 400 mg to be taken every 8 h in case of pain. The patients were asked to rate the severity of the postoperative pain on a visual analog scale (VAS) for 8th, 24th, 48th, and 72nd hours after the visit. The data were analyzed using Kruskal-Wallis, Mann-Whitney U, and Chi-Square tests.

Results

G4 resulted in lesser postoperative pain levels on 8th, 24th, 48th, and 72nd hours than the G2, G3, and G1 did. There was no significant difference between G4 and G2 and between G3 and G1 in terms of the postoperative pain levels at any time interval (P > 0.05).

Conclusion

It was determined that the postoperative values of the groups, in which EA was used, were statistically significantly lower than in the other groups. The combined use of QMix and EA provided the most significant decrease in the postoperative pain values.

Clinical relevance

Successful management of postoperative pain is an important issue for the clinician. The combined use of Qmix and EA can be recommended to the clinicians.
